Circle will begin reducing application transfer limits for the legacy USDC Cross-Chain Transfer Protocol (CCTP V1) on October 31, with plans to suspend related contracts on December 1. This move will result in stricter USDC transfer restrictions for applications still using CCTP V1. Circle stated that during the phased rollout, pending redemption requests will remain available, and minting quotas will be maintained above the total pending attestations to ensure redemptions can be processed before the full suspension.
